A: An increased concentration of salt in soil inhibits plant growth, eventually leading to plant death, and high salinity in soil is a major issue facing the agriculture industry. However, there is a subset of plants called halophytes that have adapted to growing in high-saline areas.
By 18 months, your toddler will probably start making many common consonant sounds, such as t, d, n, w, and h. Learning to make these sounds is a watershed event, one that leads to the rapid vocabulary spurt that most children go through at this stage. Don't expect to hear all these sounds in actual words yet.
When your little one does start talking, you can expect words to come slowly at first. Typically, children have around 4-6 words at 15 months and then between 20 and 50 words at 18 months. When your child hits the magic 50 word mark, he will enter a language explosion during which he will astound you with his ability to quickly learn words that you didn't even know he'd heard!
